In 1994, Robert Nelson was a young Army private in Korea who was asked to teach a 40-hour first-aid program to soldiers who were not part of a medical unit. It was the first time in his career he found himself as an educator, and he was extremely nervous. He spent three weeks preparing for it.
Today, Nelson is an accomplished military educator who earned a master’s degree in education from Penn State in 2017. He chairs the Department of Army Operations at the Sergeants Major Academy, the Army’s premier senior enlisted education program that prepares the men and women responsible for developing the next generation of soldiers. He is a published scholar, and the first faculty member in the academy’s history to earn the rank of associate professor.
Nelson spent nearly two decades as a combat medic and military health care leader, serving in Korea, Hawaii, Texas, and beyond, including surgical missions to Honduras, Bangladesh, and Malaysia. Along the way, he earned two master’s degrees and rose through the ranks to command sergeant major. As Nelson grew into those leadership roles, he came to understand that every leader is an educator. Recognizing this, he set high standards for himself, realizing that the people he was leading were learning from his actions.
The turning point for Nelson was the master’s degree he completed online through Penn State World Campus.
Selected for the Sergeants Major Academy Fellowship, Nelson earned a Master of Education in Lifelong Learning and Adult Education and a graduate certificate in distance education. During his studies, he found research that formalized what he had long sensed — that people learn not just from instruction but from watching the leaders around them. That insight became the foundation of how he designs curriculum today. Armed with a new theoretical grounding and confidence in his own abilities that Penn State helped build, he went on to earn a doctorate from Vanderbilt University, has published peer-reviewed research, and now teaches in the same Penn State program that once educated him.
Nelson shared more about his journey in the Q&A below.
You spent nearly two decades as a combat medic and military health care leader before transitioning into education. What did that chapter mean to you?
Serving as a combat medic and military health care leader was one of the most formative and rewarding chapters of my life. I served in hands-on clinical positions as a medic, practical nurse, orthopedic technician, operating room tech, and ENT technician. I worked in emergency rooms, outpatient clinics, and major hospitals, often balancing my medical duties with the broader mission of whatever unit I supported. Medics truly are jacks of all trades — we learn not only advanced medical skills but also the full operational requirements of our assigned units.
One of the highlights was participating in surgical and medical missions in underprivileged parts of the world, such as with Joint Task Force Bravo in Honduras, and missions supporting efforts in Bangladesh and Malaysia. It was an absolute honor to serve, and I felt like I was making a difference in people’s lives, one person at a time. Being a medic is fundamentally about service above self.
That chapter reinforced my core belief in leadership through service. It taught me resilience, adaptability, and the profound impact that competent, compassionate care can have, in multiple settings. Those experiences continue to shape how I approach education and leadership development today at the Sergeants Major Academy.
You already held two master’s degrees when you entered the Penn State M.Ed. program. What were you hoping to get out of it, and what did you actually find?
When I first learned that the Army was offering a Penn State degree in exchange for a multi-year teaching commitment, I was absolutely ecstatic. Although I already held two master’s degrees, I was nervous about the caliber and rigor of a program from a university as respected as Penn State. I wasn’t sure whether I could manage the demanding workload on top of my existing responsibilities. But I really wanted to find out if I had what it took.
I’m proud to say that not only was I able to meet the challenge, but I thrived in it. The experience gave me the confidence and momentum to pursue and complete my Doctor of Education at Vanderbilt University. It reaffirmed my deep commitment to lifelong learning and transformed the way I approach both teaching and leadership development.
What did you take from the program that stayed with you?
Two ideas from the program have become foundational to nearly all of my curriculum design work: the principles of andragogy and Transactional Distance Theory.
Andragogy is the art and science of helping adults learn, and it completely transformed how I approached instruction. Instead of treating students as empty vessels, we design experiences that leverage their expertise, solve real-world problems, and respect their autonomy. Transactional Distance Theory shaped my thinking about online learning. It highlights the importance of balancing structure, dialogue, and learner autonomy to reduce the psychological distance between instructor and student.
These two concepts moved me from teaching based on intuition alone to designing with intentional, evidence-based strategies. The Penn State program was rigorous, relevant, and genuinely life-changing, both personally and professionally.
Compared to my previous master’s programs, the Penn State professors were far superior. Their thoughtful feedback, responsive interactions, and clear explanations of complex topics demonstrated how deeply they cared about student success.
Now, as an adjunct faculty member myself in the same adult education and lifelong learning program, I strive to model the same level of care, engagement, and support that they provided me. A special shout-out to faculty members Dr. Ramazan Güngör and Dr. Will Diehl, who encouraged and supported me along the way.
Your research spans leadership, character, communication, and distance education. What have you found that matters most?
Three areas of research stand out to me as particularly significant.
In the area of distance education, I’ve found that threaded discussions in online learning rarely deliver superior pedagogical outcomes on their own. They often devolve into what I call an “agreement-fest” — superficial exchanges that lack depth and, with today’s technology, are increasingly populated by AI-generated responses. As alternatives, I’ve seen strong potential in reflective journaling to build metacognition and structured group projects with rotating responsibilities to foster genuine interaction. I am currently implementing and evaluating these approaches in the non-resident Sergeants Major Course.
I am also deeply interested in leadership development. The Army has excellent, detailed doctrine on leadership at every level, yet some individuals excel while others struggle despite receiving identical training. This has led me to a growing conviction that while leadership can be developed, it cannot be universally taught to the same high level in every person.
Communication presents a similar paradox. It is the single hardest thing organizations do, yet people tend to believe they are great communicators while everyone else needs to improve. My ultimate goal is to translate these insights into practical, evidence-based solutions that genuinely enhance leadership development and organizational communication. I’m particularly energized by the opportunity to test these ideas in the Sergeants Major Academy environment and share what we learn with the broader military education community.
Of all your accomplishments, what are you most proud of?
My biggest accomplishment comes from the people I have helped in one way or another over the years. I feel the absolute best when someone reaches out to me and tells me their lives were made better by something I did or said. As an educator and leader, our legacy is measured in people. If we get this right, the results are exponential.
I also have a book being published this year that I am proud of — not because the writing is that great, but because of why it was written. A former soldier of mine contacted me about 25 years after we lost contact, told me that I made a difference in her life, and suggested I write a book. Then she bugged me for eighteen months until I gave in.
In your own words, what did Penn State give you?
Penn State gave me the confidence that I could perform at truly high levels in a rigorous academic environment. It opened my eyes to what a dedicated educator could be and to the transformative power that quality education can have on individuals and organizations. That broader vision now shapes everything I do — from curriculum design at the Sergeants Major Course, to the Warrior Scholars Initiative for the academy’s highest-performing students that I helped develop, to my own teaching as a Penn State adjunct.
Penn State didn’t just prepare me academically. It helped me understand education as a powerful force for human development and leadership growth.
